Abstract
An imaging device includes an imaging unit that includes an imaging element for imaging a lower surface of continuous forms paper, an image processing unit that image-processes an image of the lower surface of the continuous forms paper captured by the imaging unit, a cable that electrically connects the imaging unit and the image processing unit with each other, and an electric box that covers the imaging element, the image processing unit, and the cable and functions as an electromagnetic shield.
Claims4
An imaging device comprising:
- an imaging unit that includes an imaging element for imaging a medium;
- an image processing unit that image-processes an image of the medium captured by the imaging unit;
- an electrical transmission line that electrically connects the imaging unit and the image processing unit with each other;
- and
- an electromagnetic shield that covers the imaging element, the image processing unit, and the electrical transmission line;
- wherein in the electromagnetic shield, the imaging unit and the image processing unit are disposed to be separated from each other, and a thermal insulation member which partitions the imaging element and the image processing unit is disposed between the imaging unit and the image processing unit.
A medium transporting apparatus comprising:
- a transporting unit that transports a medium;
- and
- an imaging device that images the medium transported by the transporting unit,
- wherein the imaging device includes
- an imaging unit that includes an imaging element for imaging a medium,
- an image processing unit that image-processes an image of the medium captured by the imaging unit,
- an electrical transmission line that electrically connects the imaging unit and the image processing unit with each other, and
- an electromagnetic shield that covers the imaging element, the image processing unit, and the electrical transmission line;
- wherein in the electromagnetic shield, the imaging unit and the image processing unit are disposed to be separated from each other, and a thermal insulation member which partitions the imaging element and the image processing unit is disposed between the imaging unit and the image processing unit.
A printing apparatus comprising:
- a transporting unit that transports a medium;
- a printing unit that performs printing on the medium transported by the transporting unit;
- and
- an imaging device that images the medium transported by the transporting unit,
- wherein the imaging device includes
- an imaging unit that includes an imaging element for imaging a medium,
- an image processing unit that image-processes an image of the medium captured by the imaging unit,
- an electrical transmission line that electrically connects the imaging unit and the image processing unit with each other, and
- an electromagnetic shield that covers the imaging element, the image processing unit, and the electrical transmission line;
- wherein in the electromagnetic shield, the imaging unit and the image processing unit are disposed to be separated from each other, and a thermal insulation member which partitions the imaging element and the image processing unit is disposed between the imaging unit and the image processing unit.
